Irelands Energy Balance and GHG Emission Inventories

1. Irelands Energy Balance and GHG Emission Inventories Martin Howley, Sustainable Energy IrelandPaul Duffy, Environment Protection Agency

2. National Institutions • Energy Statistics • Sustainable Energy Ireland (SEI) • Department of Communications Marine and Natural Resources (DCMNR) • Central Statistics Office (CSO) • Emissions Estimation • Environmental Protection Agency (EPA)

3. National Procedures for Annual Energy Reporting • Oil : Data collected by Oil Division, DCMNR and used by SEI for BalanceLegal basis : EUROPEAN COMMUNITIES (MINIMUM STOCKS OF PETROLEUM OILS) REGULATIONS, 1995. (SI No. 96/1995) • Gas : Data collected from Bord Gais Eireann (BGE) • Solid Fuel : Data collected from Bord Na Mona (for peat and briquettes) and from main solid fuel importers (for coal) • Electricity : Data collected from Power Generators (Integrated Pollution Licences IPC) • Renewables : Data collected from surveys carried out by SEI

4. Provisional Energy Balance 2002

5. 2000 Oil Balance

6. Sub-sectoral Breakdown

7. Timeliness and Quality of Data • Timeliness • Provisional balance – June • Final balance – November • Data Quality – problem areas • Lack of legal basis for most of the data collection • Subsector breakdown • Biomass • Private peat sod production • Liberalisation and fragmentation of data sources

8. Emission Methods 1 • Combustion Sources • Tier 1 methods in general • CO2 emission estimates from operators of power plants (Tier 2) • Tier 2 for domestic aviation (number of LTOs and estimated fuel use) • Tier 3 for CH4 and N2O from road transport (COPERT model)

9. Emission Methods 2 • Fugitive Emissions • gas company estimates of CH4 from gas distribution (almost negligible due to new polyethylene pipe network) • reports to OSPAR on emissions of CO2 and CH4 at sea from offshore gas production

10. Emission Factors • Combustion Sources • Country-specific emission factors for CO2 for all fuels except petroleum coke and biomass • default emission factors for CH4 and N2O (IPCC or CORINAIR) • Fugitive Emissions • Country-specific emission factors for CO2 and CH4 (emissions reported directly to the inventory agency)

11. CO2 Emission Factors Fuel t/TJ CO2 Peat Power Plants 111.6 Peat Residential 104.0 Coal Power Plants 95.0 Coal Residential 94.6 Peat Briquettes 98.9 Fuel Oil 76.0 Gasoil 73.3 Kerosene 71.4 LPG 63.7 Natural gas 54.9

13. Lessons & Actions from Harmonisation Project • Subsectoral disaggregation of the energy balance needs to be updated • Differences in emission factors and calorific values used by EPA (Ireland) and Eurostat • Methodological issues surrounding the treatments of petroleum coke, and CHP. • Balance needs to be presented in a format that facilitates automatic entry into inventory

14. Priority Areas • Sub-sectoral Energy breakdown • National Energy Balance Presentation Format • Calorific Values & Emission Factors • Lack of Legal Basis for Energy Statistics Collection • Assessment of Uncertainty
